Any certificate, statement or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of or representations by counsel, unless such officer knows that the certificate or opinion or representations with respect to the matters upon which his certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. Any certificate, statement or opinion of counsel may be based, insofar as it relates to factual matters or information that is in the possession of the Company as applicable, upon the certificate, statement or opinion of or representations by an officer or officers of the Company, unless such counsel knows that the certificate, statement or opinion or representations with respect to the matters upon which his certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous.

Any certificate, statement or opinion of an officer of the Company, as applicable, or of counsel may be based, insofar as it relates to accounting matters, upon a certificate or opinion of or representations by an accountant or firm of accountants in the employ of the Company, as applicable, unless such officer or counsel, as the case may be, knows that the certificate or opinion or representations with respect to the accounting matters upon which his certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous.

Any certificate or opinion of any independent firm of public accountants filed with and directed to the Trustee shall contain a statement that such firm is independent.

SECTION 1.03.     Notices . Any notice or demand which by any provision of this Agreement is required or permitted to be given or served by the Purchase Contract Agent or by the Holders to or on the Company may be given or served by being deposited postage prepaid, first class mail (except as otherwise specifically provided herein) addressed (until another address of the Company is filed by the Company with the Purchase Contract Agent) to Change Healthcare Inc., 3055 Lebanon Pike, Suite 1000, Nashville, Tennessee 37214, Attention: General Counsel.

Where this Agreement provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or

-14-

after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Purchase Contract Agent, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

In case, by reason of the suspension of or irregularities in regular mail service, it shall be impracticable to mail notice to the Company when such notice is required to be given pursuant to any provision of this Agreement, then any manner of giving such notice as shall be reasonably satisfactory to the Purchase Contract Agent shall be deemed to be sufficient notice.

SECTION 2.02.     Form of Certificate of Authentication . The form of certificate of authentication of the Units and Purchase Contracts shall be in substantially the form set forth in the form of Unit or form of Purchase Contract, respectively, attached hereto.

SECTION 2.03.     Global Securities; Separation of Units .

(a)    On any Business Day during the period beginning on, and including, the Business Day immediately following the Issue Date to, but excluding, the second Scheduled Trading Day immediately preceding the Scheduled Mandatory Settlement Date or, if earlier, the second Scheduled Trading Day immediately preceding any Early Mandatory Settlement Date and also excluding the Business Day immediately preceding any Installment Payment Date (provided that the right to separate the Units shall resume after such Business Day), a Holder of a Unit may separate such Unit into its constituent Purchase Contract and Note (each such separated Purchase Contract and separated Note, a “ Separate Purchase Contract ” and “ Separate Note ,” respectively), which will thereafter trade under their respective CUSIP numbers (15912K 118) and (15912K 308), and that Unit will cease to exist. In order to cause the separation of a Global Unit into its component parts, a Beneficial Holder must comply with the applicable procedures of the Depositary. Following a valid exercise of separation rights by a Holder of Global Units, the Purchase Contract Agent or Trustee, as applicable, shall register (i) a decrease in the number of Units represented by the Global Unit and the number of Purchase Contracts and Notes represented by the Component Purchase Contract and the Component Note attached to the Global Unit as Attachments 3 and 4, respectively, as set forth in Schedule A to each such attachment, and (ii) a corresponding increase in the number of Purchase Contracts and Notes represented by the Global Purchase Contract and the Global Note, respectively. If, however, such Unit is in the form of a Definitive Security in accordance with Section  3.09 , the Holder thereof must deliver to the Purchase Contract Agent such Unit, together with a separation notice, in the form set forth in Attachment 1 to the form of Unit attached hereto as Exhibit A. Upon the receipt of such separation notice, the Company shall promptly cause delivery, in accordance with the delivery instructions set forth in such separation notice, of one Separate Purchase Contract and one Separate Note for each such Unit. Separate Purchase Contracts and Separate Notes will be transferable independently from each other.

(b)    Holders that elect to separate the Note and related Purchase Contract in accordance with this Section  2.03 shall be responsible for any fees or expenses payable in connection with such separation, and neither the Company, the Purchase Contract Agent nor the Trustee shall be liable for any such fees or expenses.

SECTION 2.04.     Recreation of Units .

(a)    On any Business Day during the period beginning on, and including, the Business Day immediately following the Issue Date to, but excluding, the second Scheduled Trading Day immediately preceding the Scheduled Mandatory Settlement Date or, if earlier, the second Scheduled Trading Day immediately preceding any Early Mandatory Settlement Date and also excluding the Business Day immediately preceding any Installment Payment Date ( provided that the right to recreate the Units shall resume

-18-

after such Business Day), a Holder of a Separate Purchase Contract and a Separate Note may recreate a Unit (which will thereafter trade under the CUSIP number 15912K 209 for the Units), and each such Separate Purchase Contract and Separate Note will cease to exist. In order to cause the recreation of a global Separate Purchase Contract and a global Separate Note into a Unit, a Beneficial Holder must comply with the applicable procedures of the Depositary. Following a valid exercise of recreation rights by a Holder of Global Notes and Global Purchase Contracts, the Purchase Contract Agent or Trustee, as applicable, shall register (i) an increase in the number of Units represented by the Global Unit and the number of Purchase Contracts and Notes represented by the Component Purchase Contract and the Component Note attached to the Global Unit as Attachments 3 and 4, respectively, as set forth in Schedule A to each such attachment, and (ii) a corresponding decrease in the number of Purchase Contracts and Notes represented by the Global Purchase Contract and Global Note, respectively. If, however, such Separate Purchase Contract and Separate Note are in the form of Definitive Securities, the Holder thereof must deliver to the Purchase Contract Agent such Definitive Securities, together with a recreation notice, in the form set forth in Attachment 2 to the form of Unit attached hereto as Exhibit A. Upon the receipt of such recreation notice, the Company shall promptly cause delivery, in accordance with the delivery instructions set forth in such recreation notice, of one Unit in definitive form for such Definitive Securities.

(b)    Holders that recreate Units in accordance with this Section  2.04 shall be responsible for any fees or expenses payable in connection with such recreation, and neither the Company, the Purchase Contract Agent nor the Trustee shall be liable for any such fees or expenses.

ARTICLE III

THE UNITS AND PURCHASE CONTRACTS

SECTION 3.01.     Amount and Denominations . The aggregate number of Units and Separate Purchase Contracts evidenced by Equity-Linked Securities executed, authenticated on behalf of the Holders and delivered hereunder is limited to 5,750,000, except for Units and Separate Purchase Contracts executed, authenticated and delivered upon registration of transfer of, in exchange for, or in lieu of, other Units and Separate Purchase Contracts pursuant to Section  3.04 , Section  3.05 , Section  3.10 or Section  9.05 . Each Unit was initially issued for a purchase price of $50.00 (before underwriting discounts and commissions), which represented an issue price of $8.2378 for the Note contained in each Unit and an issue price of $41.7622 for the Purchase Contract contained in each Unit.

SECTION 3.02.     Rights and Obligations Evidenced by the Equity-Linked Securities . Each Equity-Linked Security shall evidence the number of Units or Separate Purchase Contracts, as the case may be, specified therein, with (a) each such Unit representing the rights and obligations of the Holder thereof and of the Company under one Purchase Contract, and the rights and obligations of the Holder thereof and of the Company under one Note, and (b) each such Separate Purchase Contract representing the rights and obligations of the Holder thereof and of the Company under one Separate Purchase Contract. In the case of a Unit, the Holder of such Unit shall, for all purposes hereunder and under the Indenture, be deemed to be the Holder of the Note and Purchase Contract that are components of such Unit.

-19-

Prior to the close of business on the Determination Date with respect to any Purchase Contract (whether such Purchase Contract is held as a component of a Unit or as a Separate Purchase Contract), the shares of Common Stock underlying such Purchase Contract shall not be outstanding, and such Purchase Contract shall not entitle the Holder thereof to any of the rights of a holder of Common Stock, including, without limitation, the right to vote or receive any dividends or other payments or to consent or to receive notice as a shareholder in respect of the meetings of shareholders or for the election of directors for any other matter, or any other rights whatsoever as a shareholder of the Company.

SECTION 3.03.     Execution, Authentication, Delivery and Dating . Upon the execution and delivery of this Agreement, and at any time and from time to time thereafter, the Company may deliver Equity-Linked Securities executed by the Company and the Purchase Contract Agent as attorney-in-fact for the Holders of Purchase Contracts from time to time (in the case of Purchase Contracts), to the Purchase Contract Agent and Trustee (if applicable) for authentication on behalf of the Holders and delivery, together with an Issuer Order for authentication of such Equity-Linked Securities, and the Purchase Contract Agent and Trustee (if applicable) in accordance with such Issuer Order shall authenticate on behalf of the Holders and deliver such Equity-Linked Securities.

The Equity-Linked Securities shall be executed on behalf of the Company by any authorized officer of the Company and, in the case of the Purchase Contracts, shall be executed on behalf of the Holders by any authorized officer of the Purchase Contract Agent as attorney-in-fact for the Holders of Purchase Contracts from time to time. The signature of any such officer on the Equity-Linked Securities may be manual or facsimile.

Equity-Linked Securities bearing the manual or facsimile signature of an individual who was at any time the proper officer of the Company or, in the case of the Purchase Contracts, the Purchase Contract Agent, shall bind the Company and the Holders of Purchase Contracts, as the case may be, notwithstanding that such individual has ceased to hold such offices prior to the authentication and delivery of such Equity-Linked Securities or did not hold such offices at the date of such Equity-Linked Securities.

Each Equity-Linked Security shall be dated the date of its authentication.

No Equity-Linked Security shall be entitled to any benefit under this Agreement or be valid or obligatory for any purpose unless there appears on such Equity-Linked Security a certificate of authentication substantially in the form provided for herein executed by an authorized officer of the Purchase Contract Agent and Trustee (if applicable) by manual signature, and such certificate upon any Equity-Linked Security shall be conclusive evidence, and the only evidence, that such Equity-Linked Security has been duly authenticated and delivered hereunder.

SECTION 3.04.     Temporary Equity-Linked Securities . Pending the preparation of any Definitive Equity-Linked Securities, the Company shall execute and deliver to the Purchase

-20-

Contract Agent and, in the case of Units, Trustee, and the Purchase Contract Agent and, if applicable, Trustee shall authenticate on behalf of the Holders, and deliver, in lieu of such Definitive Equity-Linked Securities, temporary Equity-Linked Securities that are in substantially the form set forth in Exhibit A or Exhibit B hereto, as the case may be, with such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as may be required by the rules of any securities exchange on which the Units or Separate Purchase Contracts, as the case may be, are listed, or as may, consistently herewith, be determined by the officers of the Company executing such Equity-Linked Securities, as evidenced by their execution of the Equity-Linked Securities.

If temporary Equity-Linked Securities are issued, the Company will cause Definitive Equity-Linked Securities to be prepared without unreasonable delay. After the preparation of Definitive Equity-Linked Securities, the temporary Equity-Linked Securities shall be exchangeable for Definitive Equity-Linked Securities upon surrender of the temporary Equity-Linked Securities at the Corporate Trust Office, at the expense of the Company and without charge to the Holder or the Purchase Contract Agent. Upon surrender for cancellation of any one or more temporary Equity-Linked Securities, the Company shall execute and deliver to the Purchase Contract Agent and Trustee, and the Purchase Contract Agent and, if applicable, the Trustee shall authenticate on behalf of the Holder, and deliver in exchange therefor, one or more Definitive Equity-Linked Securities of like tenor and denominations and evidencing a like number of Units or Separate Purchase Contracts, as the case may be, as the temporary Equity-Linked Security or Equity-Linked Securities so surrendered. Until so exchanged, the temporary Equity-Linked Securities shall in all respects evidence the same benefits and the same obligations with respect to the Units or Separate Purchase Contracts, as the case may be, evidenced thereby as Definitive Equity-Linked Securities.

SECTION 3.05.     Registration; Registration of Transfer and Exchange . The Company shall cause to be kept at the Corporate Trust Office a register (the “ Security Register ”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Equity-Linked Securities and of transfers of Equity-Linked Securities. The Purchase Contract Agent is hereby initially appointed security registrar (the “ Security Registrar ”) for the purpose of registration of Equity-Linked Securities and transfers of Equity-Linked Securities as provided herein. The Security Registrar shall record separately the registration and transfer of the Equity-Linked Securities evidencing Units and Separate Purchase Contracts.

Upon surrender for registration of transfer of any Equity-Linked Security at the Corporate Trust Office, the Company shall execute and deliver to the Purchase Contract Agent and Trustee, and the Purchase Contract Agent and Trustee shall authenticate on behalf of the designated transferee or transferees, and deliver, in the name of the designated transferee or transferees, one or more new Equity-Linked Securities of any authorized denominations, of like tenor, and evidencing a like number of Units or Separate Purchase Contracts, as the case may be.

At the option of the Holder, Equity-Linked Securities may be exchanged for other Equity-Linked Securities, of any authorized numbers and evidencing a like number of Units or Separate Purchase Contracts, as the case may be, upon surrender of the Equity-Linked Securities to be exchanged at the Corporate Trust Office. Whenever any Equity-Linked Securities are so surrendered for exchange, the Company shall execute and deliver to the Purchase Contract Agent

-21-

and Trustee, and the Purchase Contract Agent and, in the case of Units, the Trustee shall authenticate on behalf of the Holder, and deliver the Equity-Linked Securities which the Holder making the exchange is entitled to receive.

All Equity-Linked Securities issued upon any registration of transfer or exchange of an Equity-Linked Security shall evidence the ownership of the same number of Units or Separate Purchase Contracts, as the case may be, and be entitled to the same benefits and subject to the same obligations, under this Agreement as the Units or Separate Purchase Contracts, as the case may be, evidenced by the Equity-Linked Security surrendered upon such registration of transfer or exchange.

Every Equity-Linked Security presented or surrendered for registration of transfer or exchange shall (if so required by the Purchase Contract Agent) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Purchase Contract Agent duly executed by the Holder thereof, or its attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of an Equity-Linked Security, but the Company or the Purchase Contract Agent on behalf of the Company may require payment from the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Equity-Linked Securities, other than any exchanges pursuant to Section  3.06 and Section  9.05 not involving any transfer.

Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent and, in the case of Units, the Trustee shall not be obligated to authenticate on behalf of the Holder or deliver any Equity-Linked Security in exchange for any other Equity-Linked Security presented or surrendered for registration of transfer or for exchange on or after the Business Day immediately preceding the Scheduled Mandatory Settlement Date or any earlier Settlement Date with respect to such Equity-Linked Security. In lieu of delivery of a new Equity-Linked Security, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate registration or transfer instructions from such Holder, the Company shall, if a Settlement Date with respect to such Equity-Linked Security has occurred, deliver or cause to be delivered the shares of Common Stock deliverable and cash in lieu of any fractional share of Common Stock in respect of the Purchase Contracts evidenced by such Equity-Linked Security (together with the Separate Note, if such Equity-Linked Security is a Unit and if the Repurchase Right is not applicable or, if applicable, not exercised).

SECTION 3.06.     Book-Entry Interests . The Units, on original issuance, will be issued in the form of one or more fully registered Global Units, to be delivered to the Depositary or its custodian by, or on behalf of, the Company. The Company hereby designates DTC as the initial Depositary. Such Global Units shall initially be registered on the books and records of the Company in the name of Cede & Co., the nominee of DTC, and no Beneficial Holder will receive a Definitive Unit representing such Beneficial Holder’s interest in such Global Unit, except as provided in Section  3.09 . Unless and until definitive, fully registered Securities have been issued to Beneficial Holders pursuant to Section  3.09 :

(i)      the provisions of this Section  3.06 shall be in full force and effect;

-22-

(ii)     the Company shall treat the Depositary for all purposes of this Agreement (including settling the Purchase Contracts and receiving approvals, votes or consents hereunder) as the Holder of the Global Units and Global Purchase Contracts and shall have no obligation to the Beneficial Holders;

(iii)    to the extent that the provisions of this Section  3.06 conflict with any other provisions of this Agreement, the provisions of this Section  3.06 shall control; and

(iv)    the rights of the Beneficial Holders shall be exercised only through the Depositary and shall be limited to those established by law and agreements between such Beneficial Holders and the Depositary or the Depositary Participants.

SECTION 3.07.     Notices to Holders . Whenever a notice or other communication to the Holders is required to be given under this Agreement, the Company or the Company’s agent shall give such notices and communications to the Holders and, with respect to any Units or Purchase Contracts registered in the name of the Depositary or the nominee of the Depositary, the Company or the Company’s agent shall, except as set forth herein, have no obligations to the Beneficial Holders.

SECTION 3.08.     Appointment of Successor Depositary . If the Depositary elects to discontinue its services as securities depositary with respect to the Units or Purchase Contracts, the Company may, in its sole discretion, appoint a successor Depositary with respect to such Units or such Purchase Contracts, as the case may be.

SECTION 3.09.     Definitive Securities . If:

(i)     the Depositary is at any time unwilling or unable to continue as depositary for the Global Securities or ceases to be a Clearing Agency registered under the Exchange Act, and a successor Depositary registered as a Clearing Agency under the Exchange Act is not appointed by the Company within 90 days; or

(ii)    an Event of Default (as defined in the Indenture), or any failure on the part of the Company to observe or perform any covenant or agreement in the Purchase Contracts or the Purchase Contract Agreement, has occurred and is continuing and a Beneficial Holder requests that its Securities be issued in physical, certificated form,

then, in each case the Company shall execute, and the Purchase Contract Agent and/or the Trustee, as applicable, upon receipt of an Issuer Order for the authentication and delivery of Definitive Securities, shall authenticate and deliver Definitive Securities representing an aggregate number of Securities with respect to the Global Security or Securities representing such Securities (or representing an aggregate number of Securities equal to the aggregate number of Securities in respect of which such Beneficial Holder has requested the issuance of Definitive

-23-

Securities pursuant to clause (ii) above) in exchange for such Global Security or Securities (or portion thereof). Each Definitive Security so delivered shall evidence Units or Purchase Contracts or Notes, as the case may be, of the same kind and tenor as the Global Security so surrendered in respect thereof. Notwithstanding the foregoing, the exchange of Global Notes for Notes in definitive form shall be governed by the Indenture.

SECTION 3.10.     Mutilated, Destroyed, Lost and Stolen Securities . If any mutilated Equity-Linked Security is surrendered to the Purchase Contract Agent, together with such security or indemnity as may be reasonably required by the Company, the Purchase Contract Agent and the Trustee to hold them or any of their agents harmless, then the Company shall execute and deliver to the Purchase Contract Agent and Trustee, and the Purchase Contract Agent and, if applicable, the Trustee shall authenticate on behalf of the Holder, and deliver in exchange therefor, a new Equity-Linked Security, evidencing the same number of Units or Separate Purchase Contracts, as the case may be, and bearing a security number not contemporaneously outstanding.

If there shall be delivered to the Company, the Purchase Contract Agent and the Trustee (in the case of any Units) (i) evidence to their satisfaction of the destruction, loss or theft of any Equity-Linked Security, and (ii) such security or indemnity satisfactory to the Company, the Purchase Contract Agent and the Trustee at the expense of the Holder, then, in the absence of notice to the Company, the Purchase Contract Agent or the Trustee that such Equity-Linked Security has been acquired by a protected purchaser, the Company shall execute and deliver to the Purchase Contract Agent and the Trustee (in the case of any Units), and the Purchase Contract Agent and the Trustee (in the case of any Units) shall authenticate on behalf of the Holder, and deliver to the Holder, in lieu of any such destroyed, lost or stolen Equity-Linked Security, a new Equity-Linked Security, evidencing the same number of Units or Separate Purchase Contracts, as the case may be, and bearing a security number not contemporaneously outstanding.

Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Purchase Contract Agent and Trustee, and the Purchase Contract Agent and, in the case of Units, the Trustee shall not be obligated to authenticate on behalf of the Holder, and deliver to the Holder, an Equity-Linked Security on or after the second Scheduled Trading Day immediately preceding the Scheduled Mandatory Settlement Date or the second Scheduled Trading Day immediately preceding any Early Mandatory Settlement Date with respect to such Equity-Linked Security. In lieu of delivery of a new Equity-Linked Security, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate registration or transfer instructions from such Holder, the Company shall, if a Settlement Date with respect to such Equity-Linked Security has occurred, deliver or arrange for delivery of the shares of Common Stock deliverable and cash in lieu of any fractional share of Common Stock in respect of the Purchase Contracts evidenced by such Equity-Linked Security (together with Separate Notes equal to the number of, and in the same form as, the Notes evidenced by such Equity-Linked Security if such Equity-Linked Security is a Unit and if the Repurchase Right is not applicable or, if applicable, not exercised).

Upon the issuance of any new Equity-Linked Security under this Section  3.10 , the Company and the Purchase Contract Agent may require the payment by the Holder of a sum

-24-

sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Purchase Contract Agent) connected therewith.

Every new Equity-Linked Security issued pursuant to this Section  3.10 in lieu of any destroyed, lost or stolen Equity-Linked Security shall constitute an original additional contractual obligation of the Company and of the Holder in respect of the Unit or Separate Purchase Contract, as the case may be, evidenced thereby, whether or not the destroyed, lost or stolen Equity-Linked Security shall be found at any time. Such new Equity-Linked Security (and the Units or Separate Purchase Contracts, as applicable, evidenced thereby) shall be at any time enforceable by anyone, and shall be entitled to all the benefits and be subject to all the obligations of this Agreement equally and proportionately with any and all other Equity-Linked Securities delivered hereunder.

-31-

(e)     The Stock Prices set forth in the column headings of the table set forth in Section  4.07(f) shall be adjusted as of any date on which the Fixed Settlement Rates are adjusted.

(ii)     if the applicable Stock Price is greater than $40.00 per share (subject to adjustment in the same manner and at the same time as the Stock Prices set forth in the column headings of the table above), the Fundamental Change Early Settlement Rate shall be the Minimum Settlement Rate; or

(iii)    if the applicable Stock Price is less than $3.00 per share (subject to adjustment in the same manner and at the same time as the Stock Prices set forth in the column headings of the table above, the “ Minimum Stock Price ”), the Fundamental Change Early Settlement Rate shall be determined as if the Stock Price equaled the Minimum Stock Price, and using straight-line interpolation, as described in clause (i) of this Section  4.07(f) , if the Effective Date is between two Effective Dates in the table.

The Company shall cause to be delivered the shares of Common Stock, securities, cash or other property deliverable as a result of any such acceleration of the Mandatory Settlement Date in accordance with the provisions set forth in Section  4.05 , except that (i) such delivery shall be made on the accelerated Mandatory Settlement Date, and (ii) the Person in whose name any shares of Common Stock shall be issuable following such acceleration shall be treated as the holder of record of such shares as of the close of business on the Acceleration Date. Any claim for damages that Holders of the Purchase Contracts (whether as Separate Purchase Contracts or Purchase Contracts underlying Units) have for the Company’s failure to deliver Common Stock following a Bankruptcy Event as described in this Section  4.09 will rank pari passu with the claims of holders of the Common Stock in the relevant bankruptcy proceeding.

SECTION 4.11.     Return of Purchase Contract Settlement Fund .

(i)        the surrender of the relevant Units or Separate Purchase Contracts for settlement in accordance with the provisions hereof or receipt by the Company and the Purchase Contract Agent from such Holder of satisfactory evidence that such Units or Separate Purchase Contracts have been destroyed, lost or stolen, together with any indemnity that may be required by the Purchase Contract Agent and the Company; and

SECTION 5.01.     Adjustments to the Fixed Settlement Rates . (a) Each Fixed Settlement Rate shall be subject to the adjustment, without duplication, upon:

(i)        If the Company issues Common Stock to all or substantially all of the holders of Common Stock as a dividend or other distribution, or if the

-36-

Company effects a share split or share combination, then each Fixed Settlement Rate shall be adjusted based on the following formula:

Any adjustment made pursuant to this Section  5.01(a)(i) will become effective immediately after the close of business on the Record Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share subdivision or share combination, as the case may be. If any dividend or distribution described in this clause (i) is declared but not so paid or made, each Fixed Settlement Rate shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to make such dividend or distribution, to such Fixed Settlement Rate that would be in effect if such dividend or distribution had not been declared. For the purposes of this clause (i), the number of shares of Common Stock outstanding immediately prior to the close of business on the Record Date for such dividend or distribution or the open of business on the Effective Date for such share subdivision or share combination, as applicable, shall not include shares held in treasury by the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not pay any such dividend or make any such distribution on shares of Common Stock held in treasury by the Company.

-37-

(ii)    If the Company issues to all or substantially all holders of Common Stock rights, options or warrants (other than rights issued pursuant to a stockholder rights plan) entitling such holders, for a period of up to 45 calendar days from the date of issuance of such rights, options or warrants, to subscribe for or purchase shares of Common Stock at a price per share less than the average of the Closing Prices per share of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such distribution per share of Common Stock, then each Fixed Settlement Rate shall be adjusted based on the following formula:

Any adjustment made pursuant to this Section  5.01(a)(ii) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the close of business on the Record Date for such issuance. In the event that such rights, options or warrants described in this clause (ii) are not so issued, each Fixed Settlement Rate shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to issue such rights, options or warrants, to such Fixed Settlement Rate that would then be in effect if such issuance had not been declared. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of Common Stock are otherwise not delivered pursuant to such rights, options or warrants upon the exercise of such rights, options or warrants, each Fixed Settlement Rate shall be readjusted, effective as of the date of such expiration or the date it is determined such shares will not be delivered, as the case may be, to such Fixed Settlement Rate that would then be in effect had the adjustment made upon the issuance of such rights, options or warrants been made on the basis of the delivery of only the number of shares of Common Stock actually delivered.

In determining whether any rights, options or warrants entitle the holders thereof to subscribe for or purchase shares of Common Stock at less than the average of the Closing Prices per share of Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such distribution, and in determining the aggregate price payable to exercise such rights, options or warrants, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

-38-

For the purposes of this clause (ii), the number of shares of Common Stock at the time outstanding shall not include shares held in treasury by the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not issue any such rights, options or warrants in respect of share of Common Stock held in treasury by the Company.

(iii)    (A) If the Company distributes to all or substantially all holders of the Common Stock shares of Capital Stock (other than Common Stock), evidences of the Company’s indebtedness, assets or rights, options or warrants to acquire Capital Stock, indebtedness or assets, excluding (1) any dividend or distribution (including share splits or share combinations) as to which an adjustment was effected pursuant to Section  5.01(a)(i) , (2) any rights, options or warrants as to which an adjustment was effected pursuant to Section  5.01(a)(ii) , (3) except as otherwise described in Section  5.01(b) , rights issued pursuant to any stockholder rights plan of the Company then in effect, (4) any dividend or distribution described in Section  5.01(a)(iv) , (5) distributions of Exchange Property in a transaction described in Section  5.02(a) and (6) any Spin-Off to which the provisions set forth in Section  5.01(a)(iii)(B) shall apply, then each Fixed Settlement Rate shall be adjusted based on the following formula:

If FMV (as defined above) is equal to or greater than SP ₀ (as defined above) or if the difference between SP ₀ and FMV is less than $1.00, in lieu of the foregoing adjustment, provision shall be made for each Holder of a Unit or Separate Purchase Contract to receive, for each Unit or Separate Purchase Contract, at the same time and upon the same terms as holders of

-39-

the Common Stock, the kind and amount of Capital Stock, evidences of indebtedness, assets or rights, options or warrants that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Maximum Settlement Rate in effect on the Record Date for the dividend or distribution.

Any adjustment made pursuant to this Section  5.01(a)(iii) (A) shall become effective immediately after the close of business on the Record Date for such dividend or distribution. In the event that such dividend or distribution is not so made, each Fixed Settlement Rate shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to make such dividend or distribution, to such Fixed Settlement Rate that would then be in effect if such dividend or distribution had not been declared. The Company shall not make any such distribution on shares of Common Stock held in treasury by the Company.

(B) In the event that the transaction that gives rise to an adjustment pursuant to this Section  5.01(a)(iii) is a Spin-Off, each Fixed Settlement Rate shall be adjusted based on the following formula:

Any adjustment made pursuant to this Section  5.01(a)(iii)(B) shall become effective immediately after the close of business on the last Trading Day of the Valuation Period but will be given effect as of immediately after the open of business on the Ex-Date of the Spin-Off; provided that, if any Determination Date occurs during the Valuation Period, the Company will delay any settlement of a Unit or Purchase Contract until the second Business Day after the last date for determining the number of shares of Common Stock issuable to such Holder with respect to such settlement occurs. In the event that such dividend or distribution described in this Section  5.01(a)(iii)(B) is not so made, each Fixed Settlement Rate shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay such dividend or distribution, to such Fixed Settlement Rate that would then be in effect if such distribution had not been declared. The Company shall not make any such dividend or distribution on shares of Common Stock held in treasury by the Company.

-40-

(iv)        If the Company makes a dividend or distribution consisting exclusively of cash to all or substantially all holders of Common Stock (excluding (1) any cash that is distributed in, and will constitute Exchange Property as a result of, a Reorganization Event in exchange for shares of Common Stock and (2) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company), then each Fixed Settlement Rate shall be adjusted based on the following formula:

where,

If C (as defined above) is equal to or greater than SP ₀ (as defined above) or if the difference between SP ₀ and C is less than $1.00, in lieu of the foregoing adjustment, provision shall be made for each Holder of a Unit or Separate Purchase Contract to receive, for each Unit or Separate Purchase Contract, at the same time and upon the same terms as holders of Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Maximum Settlement Rate on the Record Date for such cash dividend or distribution.

Any adjustment made pursuant to this Section  5.01(a)(iv) shall become effective immediately after the close of business on the Record Date for such dividend or distribution. In the event that any dividend or distribution described in this Section  5.01(a)(iv) is not so made, each Fixed Settlement Rate shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay such dividend or distribution, to such Fixed Settlement Rate which would then be in effect if such dividend or distribution had not been declared. The Company shall not make any such dividend or distribution on shares of Common Stock held in treasury.

For the purposes of Section  5.01(a)(iv) , in no event shall a Qualified McKesson Exit or any related transaction, including the Merger, be deemed to be a liquidation, dissolution or winding up.

-41-

(v)        If the Company or one or more Subsidiaries of the Company successfully completes a tender or exchange offer for the Common Stock where the cash and the value of any other consideration included in the payment per share of Common Stock validly tendered or exchanged exceeds the average of the Closing Prices per share of the Common Stock for the 10 consecutive Trading Day period (the “ Averaging Period ”) commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer (the “ Tender Offer Expiration Date ”), then each Fixed Settlement Rate shall be adjusted based on the following formula:

Any adjustment made pursuant to this Section  5.01(a)(v) shall become effective immediately after the close of business on the Tender Offer Expiration Date; provided that, if any Determination Date occurs during the Averaging Period, the Company will delay any settlement of a Unit or Purchase Contract until the second Business Day after the last date for determining the number of shares of Common Stock issuable to such Holder with respect to such settlement occurs. If the Company or one of its Subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender or exchange offer, but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then each Fixed Settlement Rate shall be readjusted to be such Fixed Settlement Rate that would then be in effect if such tender or exchange offer had not been made.

-42-

(b)     Rights Plans . To the extent that the Company has a rights plan in effect with respect to the Common Stock on any Determination Date, Holders shall receive, in addition to the Common Stock, the rights under the rights plan, unless, prior to such Determination Date, the rights have separated from the Common Stock, in which case each Fixed Settlement Rate shall be adjusted at the time of separation as if the Company made a distribution to all holders of the Common Stock as described in Section  5.01(a)(iii)(A) , subject to readjustment in the event of the expiration, termination or redemption of such rights.

(c)     Discretionary Adjustments . Subject to applicable law and the applicable listing standards of Nasdaq (or any other securities exchange where the Common Stock is listed) and in accordance with this Agreement, the Company may make such increases in each Fixed Settlement Rate, in addition to any other increases required by this Article V , as the Company determines to be in its best interests or the Company deems advisable. The Company may also (but is not required to) increase each Fixed Settlement Rate in order to avoid or diminish any income tax to holders of the Common Stock resulting from any dividend or distribution of shares of Common Stock (or issuance of rights, options or warrants to acquire shares of Common Stock) or from any event treated as such for income tax purposes or for any other reasons; provided that, in each case, the same proportionate adjustment must be made to each Fixed Settlement Rate.

(d)     Calculation of Adjustments . All adjustments to each Fixed Settlement Rate shall be calculated to the nearest 1/10,000th of a share of Common Stock. No adjustment in a Fixed Settlement Rate shall be required unless the adjustment would require an increase or decrease of at least one percent therein. If any adjustment is not required to be made by reason of this Section  5.01(d) , then the adjustment shall be carried forward and taken into account in any subsequent adjustment; provided that on each Determination Date, adjustments to the Fixed Settlement Rates shall be made with respect to any such adjustment carried forward and which has not been taken into account before such Determination Date.

(e)     Adjustments to Prices Over a Period . Whenever the Company is required to calculate the Closing Prices, the VWAPs or any other prices or amounts over a span of multiple days (including, without limitation, the Applicable Market Value or the Stock Price), the Company shall make appropriate adjustments, if any, to each to account for any adjustment to the Fixed Settlement Rates if the related Record Date, Ex-Date, Effective Date or Tender Offer Expiration Date occurs during the period in which the Closing Prices, the VWAPs or such other prices or amounts are to be calculated.

(f)     Limitation on Adjustments . No adjustment to the Fixed Settlement Rates shall be made if Holders of Units or any Separate Purchase Contracts participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Purchase Contracts, in the transaction that would

-43-

otherwise give rise to an adjustment without having to settle the Purchase Contracts as if such Holder held a number of shares of the Common Stock equal to the Maximum Settlement Rate, multiplied by the number of Purchase Contracts held by such Holder. In addition, the Fixed Settlement Rates shall only be adjusted as set forth above and shall not be adjusted:

(i)        upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;

(ii)       upon the issuance of any shares of Common Stock or rights, options or warrants to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries;

(iii)      upon the repurchase of any shares of Common Stock pursuant to an open market share repurchase program or other buy-back transaction, including structured or derivative transactions, that is not a tender offer or exchange offer of the nature described in Section  5.01(a)(v) ;

(iv)      for the sale or issuance of shares of Common Stock, or securities convertible into or exercisable for shares of Common Stock, for cash, including at a price per share less than the Fair Market Value thereof or otherwise or in an acquisition, except as described in one of Section  5.01(a)(i) through Section  5.01(a)(v) above;

(v)       for a third party tender offer;

(vi)      upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the Issue Date, including LLC Units in the Joint Venture;

(vii)     solely for a change in, or elimination of, the par value of the Common Stock;

(viii)    for accrued and unpaid interest, if any; or

(ix)      for any other issuance of shares of our Common Stock or any securities convertible into or exchangeable for shares of our Common Stock or the right to purchase shares of our Common Stock or such convertible or exchangeable securities, except as described above, including in connection with a Qualified McKesson Exit and related transactions, including the Merger.

-44-

(g)     Notice of Adjustment . Whenever the Fixed Settlement Rates are adjusted, the Company shall:

(i)        prepare and transmit to the Purchase Contract Agent an Officer’s Certificate setting forth such adjusted Fixed Settlement Rates and/or the adjusted Fundamental Change Early Settlement Rates, the method of calculation thereof in reasonable detail and the facts requiring such adjustment and upon which such adjustment is based;

(ii)       within five Business Days following the occurrence of an event that requires an adjustment to the Fixed Settlement Rates and the Fundamental Change Early Settlement Rates (or if the Company is not aware of such occurrence, as soon as practicable after becoming so aware), provide, or cause to be provided, a written notice to the Holders of the occurrence of such event; and

(iii)      within five Business Days following the determination of such adjusted Fixed Settlement Rates and Fundamental Change Early Settlement Rates provide, or cause to be provided, to the Holders of the Units and the Separate Purchase Contracts a statement setting forth in reasonable detail the method by which the adjustment to such Fixed Settlement Rates and the Fundamental Change Early Settlement Rates was determined and setting forth such adjusted Fixed Settlement Rates and Fundamental Change Early Settlement Rates and the facts requiring such adjustment and upon which such adjustment is based.

(iv)       The Company shall adjust the Fundamental Change Early Settlement Rates at the time it adjusts the Fixed Settlement Rates pursuant to this Section  5.01 . For the avoidance of doubt, if the Company makes an adjustment to the Fixed Settlement Rates pursuant to this Section  5.01 , such adjustment will result in a corresponding adjustment to the Early Settlement Rate and the Early Mandatory Settlement Rate. For the further avoidance of doubt, if the Company makes an adjustment to the Fixed Settlement Rates, no separate inversely proportionate adjustment will be made either to (i) the Threshold Appreciation Price because it is equal to $50.00 divided by the Minimum Settlement Rate as adjusted in the manner described herein (rounded to the nearest $0.0001) or (ii) the Reference Price because it is equal to $50.00 divided by the Maximum Settlement Rate as adjusted in the manner described herein (rounded to the nearest $0.0001).

SECTION 5.02.     Reorganization Events . (a) In the event of:

(i)        any consolidation or merger of the Company with or into another Person (other than a merger or consolidation in which the Company is the continuing or surviving corporation and in which the Common Stock outstanding immediately prior to the merger or consolidation is not exchanged for cash, securities or other property of the Company or another Person);

(ii)       any direct or indirect sale, lease, assignment, transfer or conveyance of all or substantially all of the Company’s consolidated property or assets;

-45-

(iii)        any reclassification of Common Stock into securities, including securities other than Common Stock (other than changes in par value or resulting from a subdivision or combination); or

(iv)        any statutory exchange of securities of the Company with another Person (other than in connection with a merger or acquisition);

in each case, as a result of which the Common Stock would be converted into, or exchanged for, securities, cash or other property (each, a “ Reorganization Event ”), each Purchase Contract outstanding immediately prior to such Reorganization Event shall, without the consent of Holders of the Purchase Contracts, become a contract to purchase the kind of securities, cash and/or other property that a holder of Common Stock would have been entitled to receive in connection with such Reorganization Event (such securities, cash and other property, the “ Exchange Property ” with each unit of Exchange Property being the kind and amount of Exchange Property that a holder of one share of Common Stock would have received in such Reorganization Event) and, prior to or at the effective time of such Reorganization Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Purchase Contract Agent and the Trustee a supplemental agreement permitted under Section  9.01(iv) amending this Agreement and the Purchase Contracts to provide for such change in the right to settle the Purchase Contracts. Notwithstanding anything to the contrary herein, in no event shall a Qualified McKesson Exit and related transactions, including the Merger, constitute a Reorganization Event.

For purposes of the foregoing, the type and amount of Exchange Property in the case of any Reorganization Event that causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election) will be deemed to be the weighted average of the types and amounts of consideration actually received by the holders of Common Stock. The Company shall notify the Purchase Contract Agent in writing of such weighted average as soon as practicable after such determination is made.

The number of units of Exchange Property the Company shall deliver for each Purchase Contract settled following the effective date of such Reorganization Event shall be equal to the number of shares of Common Stock that the Company would otherwise be required to deliver as determined based on the Fixed Settlement Rates then in effect on the applicable Determination Date, or such other settlement rates as provided herein (without interest thereon and without any right to dividends or distributions thereon which have a record date prior to the close of business on the Determination Date). Each Fixed Settlement Rate shall be determined based upon the Applicable Market Value of a unit of Exchange Property that a holder of one share of Common Stock would have received in such Reorganization Event.

For purposes of this Section  5.02(a) , “ Applicable Market Value ” shall be deemed to refer to the Applicable Market Value of the Exchange Property and such value shall be determined (A) in the case of any publicly traded securities that comprise all or part of the Exchange Property, based on the VWAP of such securities on such Determination Date, (B) in the case of any cash that comprises all or part of the Exchange Property, based on the amount of such cash and (C) in the case of any other property that comprises all or part of the Exchange Property,

-46-

based on the value of such property on such Determination Date, as determined by a nationally recognized independent investment banking firm retained by the Company for this purpose. For purposes of this Section  5.02(a) , the term “ VWAP ” shall be determined by reference to the definition of VWAP as if references therein to Common Stock were to such publicly traded securities that comprise all or part of the Exchange Property. For purposes of this Section  5.02(a) , references to Common Stock in the definition of “ Trading Day ” shall be replaced by references to any publicly traded securities that comprise all or part of the Exchange Property.

If the Exchange Property in respect of any Reorganization Event includes, in whole or in part, securities of another Person, such supplemental agreement described in this Section  5.02(a) shall be executed by such other Person and shall (x) provide for anti-dilution and other adjustments that shall be as nearly equivalent as practicable, as determined by the officer of the Company executing such supplemental agreement, to the adjustments provided for in this Article V , and (y) otherwise modify the terms of this Agreement and the Purchase Contracts to reflect the substitution of the applicable Exchange Property for the Common Stock (or other Exchange Property then underlying the Purchase Contracts). In establishing such anti-dilution and other adjustments referenced in the immediately preceding sentence, such officer shall act in a commercially reasonable manner and in good faith.

(b)    In the event the Company shall execute a supplemental agreement pursuant to Section  5.02(a) , the Company shall promptly file with the Purchase Contract Agent an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise the Exchange Property after any such Reorganization Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly notify Holders thereof. The Company (or any successor) shall, within 20 days of the occurrence of any Reorganization Event or, if earlier, within 20 days of the execution of any supplemental agreement pursuant to Section  5.02(a) , provide written notice to the Purchase Contract Agent and Holders of such occurrence of such event and of the kind and amount of the cash, securities or other property that constitute the Exchange Property and of the execution of such supplemental agreement, if applicable. Failure to deliver such notice shall not affect the operation of this Section  5.02 or the legality or validity of any such supplemental agreement.

(c)    The Company shall not become a party to any Reorganization Event unless its terms are consistent with this Section  5.02 . None of the foregoing provisions shall affect the right of a Holder of Purchase Contracts to effect Early Settlement pursuant to Section  4.06 and Section  4.07 prior to the effective date of such Reorganization Event.

(d)    The above provisions of this Section  5.02 shall similarly apply to successive Reorganization Events and the provisions of Section  5.01 shall apply to any shares of Capital Stock of the Company (or any successor) received by the holders of Common Stock in any such Reorganization Event.

ARTICLE VI

CONCERNING THE HOLDERS OF PURCHASE CONTRACTS

SECTION 6.01.     Evidence of Action Taken by Holders . Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Agreement to be given or taken by a specified percentage of number of Purchase Contracts may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such specified percentage of Holders in Person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Purchase Contract Agent. Proof of execution of any instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Agreement and (subject to Section  8.01 and Section  8.03 ) conclusive in favor of the Purchase Contract Agent and the Company, if made in the manner provided in this Article VI .

SECTION 6.02.     Proof of Execution of Instruments and of Holding of Securities . Subject to Section  8.01 and Section  8.03 , the execution of any instrument by a Holder or his agent or proxy may be proved in the following manner:

(a)        The fact and date of the execution by any Holder of any instrument may be proved by the certificate of any notary public or other officer of any jurisdiction authorized to take acknowledgments of deeds or administer oaths that the Person executing such instruments acknowledged to him the execution thereof, or by an affidavit of a witness to such execution sworn to before any such notary or other such officer. Where such execution is by or on behalf of any legal entity other than an individual, such certificate or affidavit shall also constitute sufficient proof of the authority of the Person executing the same.

(b)        The ownership of the Units and the Purchase Contracts shall be proved by the Security Register or by a certificate of the Security Registrar.

SECTION 6.03.     Purchase Contracts Deemed Not Outstanding . In determining whether the Holders of the requisite number of Outstanding Purchase Contracts have concurred in any direction, consent or waiver under this Agreement, Purchase Contracts which are owned by the Company or by any Affiliate of the Company with respect to which such determination is being made shall be disregarded and deemed not to be Outstanding Purchase Contracts for the purpose of any such determination, except that for the purpose of determining whether the Purchase Contract Agent shall be protected in relying on any such direction, consent or waiver only Purchase Contracts which a Responsible Officer of the Purchase Contract Agent knows are so owned shall be so disregarded. Purchase Contracts so owned which have been pledged in good faith may be regarded as Outstanding Purchase Contracts if the pledgee establishes to the satisfaction of the Purchase Contract Agent the pledgee’s right so to act with respect to such Purchase Contracts and that the pledgee is not the Company or any Affiliate of the Company. In case of a dispute as to such right, the advice of counsel shall be full protection in respect of any decision made by the Purchase Contract Agent in accordance with such advice. Upon request of the Purchase Contract Agent, the Company shall furnish to the Purchase Contract Agent promptly an Officer’s Certificate listing and identifying all Purchase Contracts, if any, known by the Company to be owned or held by or for the account of any of the above described Persons;

-48-

and, subject to Section  8.01 and Section  8.03 , the Purchase Contract Agent shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Purchase Contracts not listed therein are Outstanding Purchase Contracts for the purpose of any such determination.

SECTION 6.04.     Right of Revocation of Action Taken . At any time prior to (but not after) the evidencing to the Purchase Contract Agent, as provided in Section  6.01 , of the taking of any action by the Holders of the percentage of the number of Purchase Contracts specified in this Agreement in connection with such action, any Holder of a Purchase Contract the serial number of which is shown by the evidence to be included among the serial numbers of the Purchase Contracts the Holders of which have consented to such action may, by filing written notice at the Corporate Trust Office and upon proof of holding as provided in this Article VI , revoke such action so far as concerns such Purchase Contract; provided that such revocation shall not become effective until three Business Days after such filing. Except as aforesaid, any such action taken by the Holder of any Purchase Contract shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Purchase Contract and of any Purchase Contracts issued in exchange or substitution therefor or on registration of transfer thereof, irrespective of whether or not any notation in regard thereto is made upon any such Purchase Contract. Any action taken by the Holders of the percentage of the number of Purchase Contracts specified in this Agreement in connection with such action shall be conclusively binding upon the Company, the Purchase Contract Agent, the Trustee and the Holders of all the Purchase Contracts affected by such action.

SECTION 6.05.     Record Date for Consents and Waivers . The Company may, but shall not be obligated to, establish a record date for the purpose of determining the Persons entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Agreement to be given made or taken by Holders of Purchase Contracts. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and any such Persons, shall be entitled to give, make or take any such request, demand, authorization, direction, notice, consent, waiver or other action, whether or not such Holder remains a Holder after such record date; provided, however, that unless such waiver or consent is obtained from the Holders, or duly designated proxies, of the requisite number of Outstanding Purchase Contracts prior to the date which is the 120th day after such record date, any such waiver or consent previously given shall automatically and, without further action by any Holder be cancelled and of no further effect.

ARTICLE VII

REMEDIES

SECTION 7.01.     Unconditional Right of Holders to Receive Shares of Common Stock . Each Holder of a Purchase Contract (whether or not included in a Unit) shall have the right, which is absolute and unconditional, to receive the shares of Common Stock pursuant to such Purchase Contract and to institute suit for the enforcement of any such right to receive the shares of Common Stock, and such right shall not be impaired without the consent of such Holder.

SECTION 7.02.     Notice To Purchase Contract Agent; Limitation On Proceedings . Holders of not less than 25% of Outstanding Purchase Contracts, by notice given to the Purchase

-49-

Contract Agent, may request that Purchase Contract Agent institute proceedings with respect to a default relating to any covenant hereunder; provided, subject to Section  7.08 and Article VIII hereof, the Purchase Contract Agent shall have no obligation to institute any such proceeding. No Holder of Purchase Contracts may institute any proceedings, judicial or otherwise, with respect to this Agreement or for any remedy hereunder, except in the case of failure of the Purchase Contract Agent, for 60 days, to act after the Purchase Contract Agent has received a written request to institute proceedings in respect of a default with respect to any covenant hereunder from the Holders of not less than 25% of the Outstanding Purchase Contracts, as well as an offer of indemnity reasonably satisfactory to the Purchase Contract Agent. This provision will not prevent any Holder of Purchase Contracts from instituting suit for the delivery of Common Stock deliverable upon settlement of the Purchase Contracts on any Settlement Date.

SECTION 7.03.     Restoration of Rights and Remedies . If any Holder or the Purchase Contract Agent has instituted any proceeding to enforce any right or remedy under this Agreement and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to such Holder or the Purchase Contract Agent, then and in every such case, subject to any determination in such proceeding, the Company and such Holder or the Purchase Contract Agent shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of such Holder shall continue as though no such proceeding had been instituted.

SECTION 7.04.     Rights and Remedies Cumulative . Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section  3.10 , no right or remedy herein conferred upon or reserved to the Holders or the Purchase Contract Agent is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 7.05.     Delay or Omission Not Waiver . No delay or omission of any Holder or the Purchase Contract Agent to exercise any right or remedy upon a default hereunder shall impair any such right or remedy or constitute a waiver of any such right. Every right and remedy given by this Article or by law to the Holders or the Purchase Contract Agent may be exercised from time to time, and as often as may be deemed expedient, by such Holders or the Purchase Contract Agent.

SECTION 7.06.     Undertaking for Costs . All parties to this Agreement agree, and each Holder of a Purchase Contract, by its acceptance of such Purchase Contract shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Agreement, or in any suit against the Purchase Contract Agent for any action taken, suffered or omitted by it as Purchase Contract Agent, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and costs against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section shall not apply to any suit instituted by (a) the Purchase Contract Agent, (b) any Holder, or group of Holders,

-50-

holding in the aggregate more than 10% of the Outstanding Purchase Contracts, or (c) any Holder for the enforcement of the right to receive shares of Common Stock or other Exchange Property issuable upon settlement of the Purchase Contracts held by such Holder.

SECTION 7.07.     Waiver of Stay or Execution Laws . The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or assume or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Agreement; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Purchase Contract Agent or the Holders, but will suffer and permit the execution of every such power as though no such law had been enacted.

SECTION 7.08.     Control by Majority . The Holders of not less than a majority in number of the Outstanding Purchase Contracts shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Purchase Contract Agent, or of exercising any trust or power conferred upon the Purchase Contract Agent; provided that the Purchase Contract Agent has received indemnity satisfactory to it. Notwithstanding the foregoing, the Purchase Contract Agent may refuse to follow any direction that is in conflict with any law or the Purchase Contract Agreement or that may involve it in personal liability.

ARTICLE VIII

THE PURCHASE CONTRACT AGENT AND TRUSTEE

SECTION 8.01.     Certain Duties and Responsibilities . (a) Each of the Purchase Contract Agent and Trustee undertakes to perform, with respect to the Units and Purchase Contracts, such duties and only such duties as are specifically delegated to it and set forth in this Agreement.

The Company covenants that all shares of Common Stock issuable upon settlement of any Outstanding Purchase Contract will, upon issuance, be duly authorized, validly issued, fully paid and nonassessable, free from all taxes, liens and charges and not subject to any preemptive rights.

The Company further covenants that, if at any time the Common Stock shall be listed on Nasdaq or any other national securities exchange, the Company will, if permitted by the rules of such exchange, list and keep listed, so long as the Common Stock shall be so listed on such exchange, all Common Stock issuable upon settlement of the Purchase Contracts; provided, however, that, if the rules of such exchange system permit the Company to defer the listing of such Common Stock until the first delivery of Common Stock upon settlement of Purchase Contracts in accordance with the provisions of this Agreement, the Company covenants to list such Common Stock issuable upon settlement of the Purchase Contracts in accordance with the requirements of such exchange at such time.

SECTION 11.07.     Tax Treatment . The Company agrees, and by purchasing a Unit each Beneficial Holder agrees, for United States federal income tax purposes, to (a) treat a Unit as an investment unit composed of two separate instruments, in accordance with its form, (b) treat the Notes as indebtedness of the Company and (c) in the case of each Beneficial Holder acquiring the Units at original issuance, allocate the Stated Amount of each Unit between the Note and the Purchase Contract so that such Beneficial Holder’s initial tax basis in each Purchase Contract will be $41.7622 and each such Beneficial Holder’s initial tax basis in each Note will be $8.2378 (as reflected in the cross-receipt for the Units’ initial issuance).

SECTION 11.08.     Patriot Act . The parties hereto acknowledge that in accordance with Section 326 of the U.S.A Patriot Act (the “ Patriot Act ”), the Purchase Contract Agent, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that

5.50% Senior Amortizing Notes due 2022

This Note is one of a duly authorized series of Securities of the Company designated as its 5.50% Senior Amortizing Notes due 2022 (herein sometimes referred to as the “ Notes ”), issued under the Indenture, dated as of July 1, 2019, between the Company and U.S. Bank N.A., as trustee (the “ Trustee ,” which term includes any successor trustee under the Indenture) (including any provisions of the Trust Indenture Act that are deemed incorporated therein) (the “ Base Indenture ”), as supplemented by the First Supplemental Indenture, dated as of July 1, 2019 (the “ First Supplemental Indenture ”), between the Company and the Trustee (the Base Indenture, as supplemented by the First Supplemental Indenture, the “ Indenture ”), to which Indenture reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders. The terms of other series of Securities issued under the Base Indenture may vary with respect to interest rates, issue dates, maturity, redemption, repayment, currency of payment and otherwise as provided in the Base Indenture. The Base Indenture further provides that securities of a single series may be issued at various times, with different maturity dates and may bear interest at different rates. This series of Securities is limited in aggregate initial principal amount as specified in the First Supplemental Indenture.

Each Installment Payment shall constitute a payment of interest (at a rate of 5.50% per annum) and a partial repayment of principal on the Notes, allocated with respect to each Note as set forth in the schedule below:

Any Installment Payment on any Note which is payable, but is not punctually paid or duly provided for, on any Installment Payment Date (herein called “ Defaulted Installment Payment ”)

A-30

shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Installment Payment may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Installment Payment to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Installment Payment, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Installment Payment proposed to be paid on each Note and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Installment Payment or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Installment Payment as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Installment Payment which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Installment Payment and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Notes at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Installment Payment and the Special Record Date therefor having been so mailed, such Defaulted Installment Payment shall be paid to the Persons in whose names the Notes (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2).

(2) The Company may make payment of any Defaulted Installment Payment on the Notes in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee.

The Notes shall not be subject to redemption at the option of the Company. However, a Holder shall have the right to require the Company to repurchase some or all of its Notes for cash at the Repurchase Price per Note and on the Repurchase Date, upon the occurrence of certain events and subject to the conditions set forth in the Indenture.

This Note is not entitled to the benefit of any sinking fund. The Indenture contains provisions for satisfaction and discharge, legal defeasance and covenant defeasance of this Note upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note.

If an Event of Default with respect to the Notes shall occur and be continuing, then either the Trustee or the Holders of not less than 25% in principal amount of the Notes then outstanding

A-31

may declare the Repurchase Price and all Installment Payments on this Note, to be due and payable immediately, in the manner, subject to the conditions and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee, with the consent of the Holders of not less than a majority in principal amount of the Notes at the time outstanding, to execute supplemental indentures for certain purposes as described therein.

No provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the Repurchase Price, if applicable, of and all Installment Payments on this Note at the time, place and rate, and in the coin or currency, herein and in the Indenture prescribed.

The Notes are originally being issued as part of the 6.00% Tangible Equity Units (the “ Units ”) issued by the Company pursuant to that certain Purchase Contract Agreement, dated as of July 1, 2019, between the Company and U.S. Bank N.A., as Purchase Contract Agent, as Trustee and as attorney-in-fact for the holders of Equity-Linked Securities (as defined in the Purchase Contract Agreement) from time to time (the “ Purchase Contract Agreement ”). Holders of the Units have the right to separate such Units into their constituent parts, consisting of Separate Purchase Contracts (as defined in the Purchase Contract Agreement) and Separate Notes, during the times, and under the circumstances, described in the Purchase Contract Agreement. Following separation of any Unit into its constituent Separate Note and Separate Purchase Contract, the Separate Notes are transferable independently from the Separate Purchase Contracts. In addition, Separate Notes can be recombined with Separate Purchase Contracts to recreate Units, as provided for in the Purchase Contract Agreement. Reference is hereby made to the Purchase Contract Agreement for a more complete description of the terms thereof applicable to the Units.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note shall be registered on the Security Register of the Company, upon due presentation of this Note for registration of transfer at the office or agency of the Company in the Borough of Manhattan, The City of New York, duly endorsed by, or accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder hereof or by his attorney duly authorized in writing, and thereupon the Company shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Note or Notes in authorized denominations and for a like aggregate principal amount.

The Notes are initially issued in registered, global form without coupons in denominations equal to $8.2378 initial principal amount and integral multiples in excess thereof.

The Company or Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer of this Note. No service charge shall be made for any such transfer or for any exchange of this Note as contemplated by the Indenture.

A-32

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the Person in whose name this Note is registered upon the Security Register for the Notes as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing thereon made by anyone other than the Registrar) for the purpose of receiving payment of or on account of the principal of and, subject to the provisions of the Indenture, interest on this Note and for all other purposes; and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

This Note and the Indenture and any claim, controversy or dispute arising under or related thereto shall be governed by and construed in accordance with the laws of the State of New York.

Capitalized terms used but not defined in this Note shall have the meanings ascribed to such terms in the Indenture.

No recourse shall be had for the payment of any Installment Payment on this Note, or for any claim based hereon, or upon any obligation, covenant or agreement of the Company in the Indenture, against any incorporator, stockholder, officer or director, past, present or future of the Company or of any predecessor or successor, either directly or through the Company or any predecessor or successor, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment of penalty or otherwise; and all such personal liability is expressly released and waived as a condition of, and as part of the consideration for, the issuance of this Note.

The Company and each Beneficial Holder agrees, for United States federal income tax purposes, to treat the Notes as indebtedness of the Company.

In the event of any inconsistency between the provisions of this Note and the provisions of the Indenture, the Indenture shall prevail.
